MACHINE FOR DOUBLING AND WINDING YARN OR THREAD UPON BDBBIN,S.

-n 3IFIGATEON forming part of Letters Patent No. 313,869, dated March17, 1885.

Application filed October 19, 18 2.

such as will enableothers skilled in the art to which it appertains tomake and use the same,

reference being had to the accompanying drawings, and to letters orfigures of reference marked thereon, which form a part of thisspecification.

Our invention relates to thatclass of ma chines employed for doublingand winding thread commonly known as drum-winding machines. I

In an application for patent filed by us of even date herewith we haveshown and claimed certain improvements in devices whereby upon thebreakage or absence of a thread the bobbin is lifted clear of thedriving-drum.

The presentinvention is designed as an improvement thereon; and itconsists in the combination, with a detector-plate and a bobbin frame orcarrier, of mechanism whereby said carrier is held with its bobbin outof con tact with the driving-drum, whereby the momentum of the bobbin isarrested, the move ment of the carrier in a direction away from the drumlimited, and whereby said carrier may be moved into a positionrelatively to its support with the bobbin out of contactwith the latter,substantially as hereinafter fully de scribed.

In the accompanying drawings, Figure l is a sectional elevation of adouble machine illustrating one construction of bobbin-lifting devicesand a modification thereof. Fig. 2 is a like view, on an enlarged scale,of the bob- Fig. 3 is a plan view of Fig. 2. Fig at is a sectionalelevation of a modification in the construction of the bobbin frame orcarrier shown on the right of Figs. 1 and 2 and 011 the left of Fig. 8.Fig. 5 is a like view showing the bobbin frame or carrier of Fig. 4lifted 'clear of the driving-drum and lever-frame. Fig. 5 is (No model.)Patented in England July I), I831, No. 3,132.

aperspective view of thebrake-levcrD shown in Figs. 4 and Fig. (3 is asectional elevation of a further modification in the construction of thebobbin-lifting devices. Fig. 7 is a plan view thereof. Fig. 8 showsanother modiiication of the said bobbin-lifting appliances. Figs. 9, 10,11, and 12 are detail views of an improved detector-plate, and 13 is ade tached view showing the mode of pivoting the detector-plate.

Like letters of reference indicate like parts wherever such may occur inthe above figures of drawings.

A, Fig. 1, indicates the main frame, of any suitable material, andconstructed to support the operative mechanism, and in order that thislatter may be better understood we will first describe that constructionshown on the right of Figs. 1 and 2 and on the left of Fig. 3.

C indicates the drivingdrum,and H the bobbin, the spindleh of whichrotates in bearing-grooves b formed in the side bars b of a frame orcarrier, B, one of which side bars is extended to form a handle, B Theside bars b are connected together at their rear ends by a cross-bar,B", provided on its under side with bearings in which is secured apivot-pin, 1), upon which is pivoted the rear end or long arm of anangular lever, D, that has its fulcrum at d in a bracket, a, attached tothe beam A, that extends from end to end of the machine. The lever D iscomposed of two angular side bars, forming short and long arms ontheinner and outer side of the fulcrum cl, respectively. The sidebars (Zon the inner side of the fulcrum, which constitute theshort arm of thelever D, are connected by a crossbar, at, a like crossbar connectingsaid arms on the outer side of the fulcrum d,'as plainly shown in Figs.2 and 3.

Upon the pin b, between the arms d of lever D, is pivoted atripping-lever, F, composed of the socketed shankf and the pinf,adjustable within the socket of the shank by means of a set-screw,f-.The free end of the tripping-lever projects outwardly, and is adapted tobear against a stop, e, that projects from the detector-plate E, andlies upon the upper face of the beam A, in which said plate E ispivoted. The side bars I; of the bobbin frame or carrier may be weightedin any suitmentum of said bobbin.

able manner. WVe preferably provide these bars with meanssuch as theholes if, or equivalent means-for attaching a weight,b ,thereto, bymeans of a cord, as shown, or by means of a link or chain. When duringthe winding one or more threads break or is or are absent, thecorresponding detector wire or wires drop down into the path of acam-shaft or a prismshaped shaft, G, (preferablythe latter.) This shaft,impinging upon the lower end of the detector wire or wires, tilts thedetector-plate E, its stop 6 being moved out of the way of thetripping-leverF to release the carrier and lever. Both the carrier B andlever D are now free to swing on the fulcrum d, the inner ends of thelever Dascendingto meetthe bobbin-carrier and support the bobbin, and atthe same time 'act as a brake to arrest the mo- This movement of thelever D and bobbin-frame is greatly accelerated by the action of theweight b, so that the bobbin is rapidly carried out of contact with thedriving-drum to enable the operator to find and tie the broken or absentthread or threads, as hereinafter explained, and at the same time saidweight not only holds the bobbin firmly on the drum while in contacttherewith, but also holds said bobbin firmly on the lever, and assistsin checking or arresting itsmomentum.

By an inspection of the drawingsit will be seen that the bobbin-carrieris pivoted to the long arm of the lever D, and that, the latter has itsfulcrum at d. Hence, if the trippinglever is released, thebobbin-carrier B will move outwardly or away from the drum, anddownwardly, while the outer end of the lever D moves downwardly and itsinner end upwardly against the bobbin, forthe purposes set forth,

the bobbin resting upon the lever end of.

Upon the pin 1), between the arms d of the lever D, is hung a flat legor stop, B, the pin passing through avertical slot, If, in said stop.

. When the carrier and lever are tilted, as.

above described, to carry the bobbin away from the driving-drum andsupport it in that ,position, the lower face of the stop B comes incontact with the bracket a, andvits upper ,face with the under side ofthe cross-bar B thus limiting the downward movement of the carrier andlever, and supporting the same in r, the end d of the lever D.

the proper position.

Toenable the attendant to hold the bobbin .out of contact with the leverand rotate the same to find the broken or absent thread or threads,whensaid lever and carrier have been tilted as described he depresses thehandle B slides over the outer upper corner of the stop B, downwardly ashort distance, and carries with it the short arm of lever D and pin b,

, which latter moves down in the slot of the carrier bearing against theedge of the stop,

stop B a short distance, the crossbar of the e which thus affords acertain but small amount of leverage to support the carrier. Thisleverage and the frictional contact of the crossbar with the stop holdthe carrier up with the bobbin out of contact with the lever, but not sosecurely that by applying a certain amount of force to the handle thecarrier cannot be returned to its normal position. In this movement ofthe carrier with the lever the bobbin is carried away from the latter,owing to the difference in the distances traveled by the short arm ofthe lever and the longerside bars of the bobbin-carrier. This downwardmovement of the pivot-pin b and lever D in the slot of the stop will bereadily understood when it is borne in mind that the stop B, when incontact with the bracket a, constitutes the support as well as thefulcrum from which the bobbin'carrierBis supported and upon which it canbe tilted, and inasmuch as the pivotpin 1) for the long arm of the leverD passes through a slot in the stop, and the outer end of both thebobbin-carrier and lever can move downward when the carrier is tilted inthe stop B, the pin will necessarily partake of this downward movementin the slot of the said stop, which movement is, however, a limited one,but sufficient to afford a bearing to hold the 'bobbin earrier withthebobbin away from the lever D, as above stated. When the absent or brokenthread or threads have been found and tied, and it is desired to returnthe bobbin in contact with the driving-drum, the

attendant lifts the carrier B by means of the handle B the pin 1)rising, in slot 1/ of the stop B until the cross-bar B of carrier Bagain lies onthe upper face of said stop B and the bobbin on the end atof lever D. By a slight further movement of carrier B in the directionof the drum 0 the stop B is lifted clear of the bracket (1, andthe-carrier and lover will swing toward the drum sufficiently-to causethem to continue tomove in that direction by their own weight or by thelatter assisted by the weight I).

Instead of supporting the bobbin-carrier B and lever D upon the stop B,they may be supported as shown in Figs. 4 and 5, wherein one of the sidebars I) of the bobbin-carrier B has an outwardly and downwardlyprojecting extension or arm, B and upon the outer face of the transversebar B of the carrier at its outer end are formed bearing-lugS,FigS. 2,3, 6, 7, and 8, inwhich is secured the pivotpin 1). Upon this pin ispivoted the trippinglev'er F, the arm f of which extends rearwardly andbears against the tripping-arm e of the detector-plate E. As shown, thisarm is made tapering, for purposes presently explained.

The lever D is pivoted upon a bracket, a, and is constructed as follows:Theinner short arm, d of the lever has a bearing-surface, (1 upon whichthe bobbin is supported when moved out of contact with the driving-drum.d are depending lugs constituting pivotal bearings, by means of which itis pivoted to bracket or. The outer or longer arm of the lever D isformed by two diverging arms, (1

(Z having lugs d projecting vertically there from and forming bearings,by means of which the said longer arm is pivoted to the outer end of thebobbin-carrier by means of the pivot-pin 2). One of the lugs d has, armsD" d", as plainly shown in Fig. 5", projecting vertically therefrom, theformer serving as a handle and the latter as a rest or foot forsupporting the lever and bobbincarrier when the lat ter has beentripped.

The operation of these devices is plainly illustrated in Figs. at and 5,and may be briefly described as follows: W'hen the parts are in theirnormal position, as shown in Fig. at in full lines, the bobbin is incontact with the driving-drum, held there by its own weight or by saidweight b and an additional weight suspended from the carrier at 11",-but said bobbin is not in contact with the bearing-surface of the lever.\Vhen a thread or threads break or are absent, and the detector wire orwires thereof fall into the path of the rotating an gular bar G, thedetectorplate E is tilted upward and its arm 6 moved away from the arm fof the tripping-lever F, thus allowing the bobbiucarrier B, and with itthe lever D, to swing on the pivot of bracket 1, the inner arm, (1 ofthe lever rising to meet the downwardly-moving bobbin and support thesame.

It is obvious that since the carrier B is pivoted at its outer end onlyto or with the lever D the inner end thereof, through the bobbin, issupported clear of the inner end of the lever D by the driving-drum, andthat, as soon as said carrier moves outward and away from the drum, thebobbin moves downward until, when clear ofthe drum, it meets and issupported by the upwardlyinoving leverend or bearingsurface d The leverD, being pivoted about its longitudinal center, can there fore onlyswing downward on its pivot, and as its outer end swings downward itsinner end necessarily swings upward to meet the downwardly-movingbobbin. In this manner the bobbin is not only supported by the end oflever D, but the extended bearing-surface d thereofacts as a brake toarrest the momentum of the bobbin. The downward motion of the outer endof the carrier and lever is limited by the extension or foot (1 comingto rest upon the beam A which extends or may extend from end to end ofthe machine, the bobbin being thus held out of contact with thedriving-drum, as shown in dotted lines in Fig. 4. In this downwardmovement of the outer end of carrier B the armf' of the tripping-leverpasses under the arm 6 of the during which movement of the arm thecarrier and lever are slightly lifted or tilted on their respectivepivots, and when said arm has passed over the beam the carrier and leveragain drop down, the arm bearing against the vertical face of the beamand holds the carrier in the position shown in Fig. 5. To return theparts into their normal position, the attendant lifts the lever D, andwith it the carrier, by means of the handle D until the arm B is clearof the beam A, when both lever and carrier will swing forward on theirpivots, and said parts will then be in the position shown in dottedlines, Fig. 4. By lifting the carrier on pivot b, and then tilting theinner end of the same and that of the lever D downward until the arm fof lever F bears against the arm 0 of detectonplate E, and allowing thecarrier to drop, the bobbin will again lie on the driving-drum, as shownin full lines, Fig. 4:.

Ve will now (.lQStllbG that construction of mechanism shown on the leftof Figs. 1 and 2 and on the right of Fig. 3. In this construction thebobbin-carrier B is pivoted upon a fulcrum or axis, Z), that has itshearings in two arms, a", pivoted at a in bearings a secured to the beamA, that extends from end to end of the main frame. Upon the pivot-pin bis pivoted the trippinglever F, constructed substantially like the leverdescribed hereinbefore, the outer or free end of which abuts against a;trippingarm, (2, secured to and projecting from the detector-plate E,the outer end of said arm lying upon the beam A", as shown.

Upon the beam A is secured an inclined flat plate, I, that extends underthe bobbin H in proximity to the driving-drum G, and is of such a widthas to adapt it to perform the functions of a brake to arrest themomentum of the bobbin when the carrier B descends 'to carry the bobbinonto said plate.

As shown in Fig. 1, the bobbin is held in coutact with the driving-drum,and is rotated thereby to wind the threads; but when a thread breaks oris absent its detector-wire falls and comes in contact with thecam-shaft G, that causes the detector-plate to swing upward, therebylifting the arm 6 away from the tripping-lever F, which slides undersaid arm and allows the carrier B to swing toward said plate E orupward, the bobbin H riding over the driving-drum onto the fixed brakesupport I. Here, as in the construction shown on the right of Figs. 1and 2 and on the left of Fig. 3, the tripping-lever slides under thetrippi ng'arm e of the detector-plate and causes said plate to movefarther away from the prismshaped shalt or bar G, by which movement theof said figures; or, as shown in Figs. 4 and 5, it may be wedge-shapedor made tapering from the plate outwardly. Any one of these arrangementsmay be adopted to insure the removal of the detector-wires from the path'of the angularbar G after the plate has been tilted by the latter.'

As shown on the left of Figs. 1 and 2, the outward movement of thecarrier B is effected bythe weight of the bobbins and that of the freeend of the carrier, or by said weights and the attached weight b, and assoon as the lever F is tripped the arms a under the weight describedrotate outwardly on their pivot a carrying with them the carrier B,which at the same time swings downwardly on its fulcr-um b. Thisdownward and outward movement causes the bobbin to roll off thedrivingdrum 0 onto the inclined supporting brakeplate I, that holds thebobbin and carrier, and by reason of the weight alluded to at once anrests the momentum of said bobbin.

Upon the fulcrum a is hung a leg or stop, J, the lower end of whichextends downward in front of the beam A. WVhen the bobbincarrier istilted outwardly upon the breakage or absence of a thread through theoperation of the detector-plate and tripping devices, the cross-bar Bimpinges against the upper edge of the leg and-tilts the same outward,the car-' rier being held in this position by gravity or by the latterand the additional weight b. When so tilted outward, the longitudinalaxis of the leg J lies nearly parallel with the upper face of the beamA", and the cross-bar B of the carrier B above and slightly in front ofthe pivot a. By lifting the carrier by means of the handle Bsufficiently to allow the leg J to swing inward into the verticalposition the cross-bar B of the carrier will come to rest upon the leg,and said carrier will be held in a sufficiently elevated position tohold the bobbin clear of the brake-support I and enable the attendant torotate said bobbin and find and tie the broken or absent threads. Bypushing the handle B inward the crossbar B of the carrier will slideover the upper face of the leg J, its inner end dropping down with thebobbin on the brake-surface I. The carrier may now be liftedsufficiently to bring the tripping-lever F against the tripping-arm e ofthe detector-plate E and allowed to drop, and thebobbin will again lieon the drivingdrum, with the extension a of one or both arms at belowtheir pivotal connection a ,bearing against the vertical face of thebeam A, as shown by dotted lines on the left of Fig. 2 and in full linesin Fig. 6.

As shown in Figs. 6 and 7, about wire, D connected with an arm, a,projecting from the arms a of the carrier B, and a horizontal wiresupported from the detector-plate, as described in the Letters Patenthereinbefore referred to, may be employed instead of the tripping-leverand arm for tripping the bobbin-carrier, and instead of a bent wire, D astraight wire may 'be employed, said wire being held by a verticaltripping-arm, e, projecting from plate E, as shown in dotted lines, Fig.6.

Instead of the construction of bobbin-carrier and tripping mechanismtherefor hereiuabove described, the construction of carrier and trippingmechanism shown in Fig. 8 may be employed, and this will be foundequally efficient. This mechanism is similar to that shown on the leftof Figs 1 and 2 and on the right of Fig. 3, except-that the bobbin H issuspended between the detector mechanism and the fulcrum b of thebobbin-carrier B. In this arrangement two bobbins may also be wound uponopposite sides of the drivingdrum, although we have shown but one, andthis construction is equally if not more conveniently applied when onlyone bobbin is wound. In said construction a beam, A extends the fulllength of the machine above the drum 0, and carries brackets A for theoperative mechanism. The arms a are pivoted at a upon the bracket A, andthe side bars 12 of the carrier B are pivoted to said arm at b. One ofthe arms, a, is extended to form a handle, B From the side bars of thebobbincarrier project arms I)", to which the weight b" is attached, topress the bobbin against the periphery of the driving-drum O; and F is atrippinglever or bar pivoted upon the carrier-fulcrum b, and abuttingagainst the tripping-arm e, secured to the detector-plate. A notchedstop, J, is pivoted on a pin attached to one of the side bars b of thecarrier B. The stop has a stud or projection, j, that limits itsdownward movement by coming in contact withQthe edge of one of the sidebars b. When the bobbin-carrier is released by the tripping devices, asdescribed, and descends, the notch j engages the Wedge-shaped projectionor spur is, formed on abracket, K, to support the carrier andhold thebobbin clear of the drum on the inclined brake-support I. When themomentum of the bobbin has been arrested, the bobbin-carrier may beraised until the nosej of the stop J rests upon the end is of the spur kon bracket K, when the bobbin will be clear of the brake I, and may berotated to find and tie the broken or absent thread end or ends. Whenthe bobbin-carrier is moved back by the handle B, the end of the stopslides off the spur is, leaving the carrier free to swing in toward thedriving-drum O, and carry the bobbin into contact therewith. I

As shown by Figs. 9, 10, 11, and 12, which illustrate the detector-plateby an edge view, front, and elevations, and a vertical transversesection, respectively, said plate E has a trunnion or pivot, 0 and aprojecting lug or stud, 6 at each end, instead of a pivot only, asdescribed in our Letters Patent here inabove referred to. When the plateE is hung in-its bearings formed in arms A, that project from the beamsA A the pin 6 lies under said bearings, and thus locks the plate againstvertical movement, leaving it free to swing in the direction ofthe drum,which movement is not sufficient to clear the pins a from under saidbearings, ahalfturn of the detector-plate being required for thelatterpurpose, when the detector-plate may be lifted out of its bearings, asshown in Fig. 13.

Instead of the locking pins or studs 6", the

plate may be provided at each end with av half-turn toward the drumbeing required to permit its removal therefrom, the same as with thelocking-studs above described. The de tector-plate is provided withlongitudinal ribs 6, notched or channeled, as at e, for the passage ofthe wires E, which wires have a curl or are bent, as at 0 to preventtheir being lifted out of the plate by the tension of the thread, andalso to hold said wires against tension. The wires are held in theirnotches by a retaining-plate, E secured to plate E by'a thumbscrew, E.

The threads to be doubled or wound are drawn from cops or from bobbinsor swifts arranged in any ordinary manner. Said threads pass eachthrough a slit in a cleaning or guide plate, K, and overaflannel-covered tube, L, to give friction and clean the threads. Fromthe tube the threads pass through the guide hooks or curls e of thedetector-wires E, thence over the pulleys M, mounted in bearings formedin arms m, secured to the upper beam, A of the main frame A. From thepulleys M the threads descend through guideloops n, adjustably securedto a bar, N, that has the usual traversing motion for distributing thethreads, from which guide-loops said threads pass onto the bobbins, allas plainly shown in Fig. l.

Having now described our invention, what we claim, and desire to secureby Letters Patent of the United States, is

1. The combination, with a driving-drum, a bobbin-carrier, a stop tohold the latter with its bobbinin contact with the former, and trippingdevices to trip the stop and permit the carrier to move away from thedrum, of a supwith the support and the driving-drum, subsiant-ially asand for the purpose specified.
